If you use a 12k btu instead of a 9k btu, i feel that it will save more energy over the long run as compressor cut off faster and once the compressor is running at low speed of cut off, the energy consumption is lowered greatly.

Great! Thanks for the input

1. Can use back provided no existing leakage issues but ask them to clean the drainage pipes for you.
2. If possible, best if to replace all piping including drainage.
3. Based on your usage, 5 ticks will be better.

can advise for suitable air-conditioning method as i am looking to hack and combine my new BTO flat master bed room and bed room 2 (walk-in-wardrobe)?

gain city sales person told me to get 2 x 9000 BTU unit in each room.
And include a sliding door in between the rooms and close it when switching on the aircon (which defeats the purpose of hacking the walls).

is it possible that i get a bigger unit and still cool down the whole room?
will a bigger unit consume a lot of power to cool down a combination of 2 rooms?

Need help ASAP. Do I need to submit Aircon installation report to HDB within 14 days after aircon installations(http://www.hdb.gov.sg/cs/infoweb/res...allation-works) or does it apply only to certain groups of flats? I ask abt the report submission but the installer say there's no need for that. My flat is 20 yrs old and came with the 20amp power point.
